TH'EODOR MUENOH, OF VIENNA, AUSTRIA.

PICTURE-EXHIBITOR.

SPECIFICATION forming part of Letters Patent No. 231,343, dated August 17, 1880. Application filed April 30, 1880. (No model.)

To all whom it may concern:

Be it known that I, THEODOR MUENGH,1G- siding at Vienna, in the Empire of Austria, and a subject of the Emperor of Germany, have invented a certain Improvement in Picture- Exhibitors, of which the following is a specification.

My invention relates to improvements in devices for exhibiting photographic or other pictures, maps, drawings, or other like flat objects and it consists in the arrangement and construction of a frame or holder that supports the frames in which the photographs or other like objects are held and their combination with a case or other like receptacle, as fully described hereinafter, and shown in the accompanying drawings, in which- Figures 1, 2, and 3 show, in elevation, diagrams illustrating the holder and pictureframes in various positions. Fig. 4 is a plan View of the same. Fig. 5 is an isometrical View, showing the arrangement of holder and frames. Fig. 6 is a detail view, and Figs. 7, 8, and 9 show the combination of the holder and the frames with a casin g or receptacle for the same. I

In the above-described figures of drawings like letters of reference are employed to indicate like parts wherever such may occur.

A represents the holder, which consists of a rectangular oblong open frame, ofwood or metal or other suitable material, that is provided on the two opposite longer sides with a series of pivot-holes for the reception of the pivot bars or shafts a, to which the pictureframes are attached and upon which said frames may be rotated.

B represents the picture-frames, constructed like those of the usual photograph-albumsthat is to say, they are so arranged that each individual frame B will hold two pictures back to back. These frames B are connected in any desired or preferred manner with the pivot bars a, and in practice I insert these bars between the'two thicknesses of material of which the frames are composed, at a point near their lower edges, and projecting slightly on opposite sides, and I arrange the frames B at such a distance from each other in the holder A as to adapt them to rotate upon their pivots a through an angle of about one hundred and twenty degrees, for the purpose of exhibiting the pictures at the front and at the back of the frame, each of which is constructed to hold two such pictures, as above described.

It is evident that for the purposes of exhibition only the devices, so far as I have now described them, are complete in themselves, inasmuch as the holder A, with its frames B, may be placed upon any suitable support, either horizontal or inclined.

In most cases it is necessary and desirable that the pictures in the frames B should be protected fromdust as well as other deleterious influences that might injure them, and I prefer to use in combination therewith a suitable inclosing-case.

For picture-gallery purposes or under special circumstances it may also be desirable that the holder and its frames should be so constructed as to be readily shifted from place to place, and in the accompanying drawings I have shown, in Figs. 7 and 8, the combination of the holder and frames AB with an inclosingcase, and in Fig. 9 the combination of these elements with a readily-transportable case. In these figures 0 represents the inclosing-case, provided with a suitable lid hinged thereto and of any desired or preferred configuration compatible with the general form of holder and frames, and so arranged that when the case is open facilities will be provided for turning the frames B on their pivots for exhibiting the pictures. To that elfect I employ a case, 0, open at front and top, having an inclined groove, 1), extending from its upper edge at a point near the back of the case where the lid is hinged down to its bottom, said groove b being of such width as to receive and hold the holder A when slid into it, as shown in Figs. 7,8, and 9. I

The former two figures illustrate the combination of a holder, A, and frames B with an inclosing-case, G, for exhibiting pictures of medium size which do not require a frame large enough to make the case too heavy, though it is evident that even this form of case may be constructed to receive any desired size of holder and frames.

For purposes of shifting, the case may be mounted either directly on wheels or on a wheeled carriage or stand,

In Fig.9 I have illustrated a convenient form of portable case, C, for containing the holder and frames and for shifting them from one place to another.

It will be seen that the form of case C may be varied so long as it is adapted to securely hold the hohler and frames in a proper position to adapt said frames being turned for to operate substantially as described, aml for the purpose specified.

2. The combination of the holder A and its pivoted frames B with an inclosing-case, 0, provided with the inclined groove 1), for the reception of said holder when arranged, constructed, and operating as described, and for the purpose specified.

3. The combination of the holder A and its pivoted frames B with a wheeled containingcase, 0, having the vertically-inclined groove I1, all constructed, arranged, and operating substantially as described, for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
